High-Fixed Windows
High fix is a fixed-window profile that can coordinate with adjacent operating windows. The name does not require installation high on a wall. Compare frame sightlines and visible glass using the product drawings.
Best uses
- Fixed sections beside operating windows
- Coordinated frame sightlines
- Rooms with ventilation provided elsewhere
- Openings with a safe plan for cleaning fixed glass
Coordinate Frame Sightlines
Compare the high-fix frame profile with adjoining operating windows. High fix is a profile choice, not a required mounting height.
Plan Privacy
Placement, glass choice and views from outside affect privacy. A high-fix profile does not by itself provide privacy.
Compare Certified Ratings
Compare whole-product U-factor, SHGC and air-leakage ratings for the selected glass, frame and size. The operating style does not establish certification or energy savings.

- U-factor
- Heat transfer through the complete window. Lower values indicate better insulation. U.S. values use Btu/(h·ft²·°F); metric equivalents use W/(m²·K).
- SHGC
- Solar heat gain coefficient, from 0 to 1. Lower values admit less solar heat.
- VT
- Visible transmittance, from 0 to 1. Higher values admit more visible light.
These reference configurations have no grilles. Each row preserves the NFRC manufacturer code for its frame, glass and gas combination. Select the matching series and glass package, and confirm the CPD number and label for your order. Different glass, grilles, frame systems and joined assemblies can have different ratings.
For Midwest and Northeast projects, compare heat transfer, winter sunlight and summer exposure together. A lower U-factor indicates less heat transfer. A lower SHGC admits less solar heat; a higher SHGC admits more. VT describes visible light transmission. Orientation, shading and local code affect the choice. NFRC ratings alone do not establish ENERGY STAR eligibility.
